I found solution

1- use momentjs to convert it to utc and use format YYYYMMDDHHmmss

        var fromDate = moment(searchText.fromDateSearch).utc().format('YYYYMMDDHHmmss');
        var toDate = moment(searchText.toDateSearch).utc().format('YYYYMMDDHHmmss');
        url = ' api/' + fromDate + '/' + toDate + '/searchDateRange' ;

2- in webapi level convert string to datetime

[System.Web.Http.Route("api/{fromDate}/{toDate}/searchDateRange")]
            public IEnumerable<FormViewModelBase> GetFormsByDateRange(string fromDate, string toDate)
            {

                var fromDateSearch = DateTime.ParseExact(fromDate, "yyyyMMddHHmmss", CultureInfo.InvariantCulture);
                var toDateSearch = DateTime.ParseExact(toDate, "yyyyMMddHHmmss", CultureInfo.InvariantCulture);
            }
